浙江大学硕士学位论文 Abstract Supported by the project entitled"Fundamental research on design and manufacture of a bionic micro jumping mechanism based on the locust lever-ejection jumping mechanism"from National Natural Science Foundation of China(Grant No.50975251),we make a research on locust's jumping mechanism and its bio-jumping mechanism.Firstly,the images of locust's take-off phase are acquired by a high-speed photography camera,and the motion parameters of saltatorial leg are obtained.Then,the locust is simplified as a plane rigid body mechanism and the relationship between the locust centroid and joint rotation angle is established.By way of this,we can get the characteristic of the locust's movement,and a reasonable explanation of this advantageous character is presented.Then,we put forward the design of a bionic locust-jumping leg according to the biological experiments and kinematics analysis.Based on this,a bionic locust jumping mechanism is designed.Also,the dynamics analysis and experimental tests of the jumping mechanism are performed.The results illustrate the similarity between the locust and the mechanism.Subsequently,the jumping performance is tested and the adverse factors are analyzed.Lastly,the energy utilization rate and jumping height of the bionic jumping mechanism are improved. In Chapter 1,the background and significance of this research,the current research situation about the biological jumping movement and the jumping robot research were introduced,and then the research contents of this thesis were proposed. In Chapter 2,Oxya chinensis was selected as the research object,and the image of locust's jumping phase was obtained by a high-speed photography camera.Then,the motion parameters of saltatorial leg were acquired.To establish the relationship between the locust centroid and joint rotation angle,the locust is simplified as a plane rigid body mechanism,the centroid movement was studied by using the kinematics analysis.By way of this,the theoretical conclusion of the locust's jumping is obtained. In Chapter 3,Based on the kinematic characteristic of the locust,the saltatorial leg of the jumping mechanism is designed and its structure is optimized.Then,the whole jumping mechanism is designed. In Chapter 4,.the dynamic model of the jumping mechanism is established and the dynamic Ⅲ

浙江大学硕士学位论文 results is acquired by MATLAB.The jumping experiment of the jumping mechanism is made and the results show that the mechanism has a similar motion with the locust. In Chapter 5,.the whole jumping phase of the bionic mechanism is obtained,and we analyze the adverse factors of the mechanism.To obtain better quality distribution and make the jumping mechanism lighter,we improve it.Jumping experiment results show that the improved jumping mechanism has a better energy utilization rate and a higher jumping height. In Chapter 6,the chief work of this thesis was summarized,and research objects were proposed in future. Keywords:locust;jumping mechanism;bionic;jumping robot; IV
